Storage conditions and validity
Storage Conditions: 2 ºC ~ 30 ºC
non-corrosive gas environments dark, damp storage.
Duration: 18 months After opening period: three months.
Applicable instrument
Suitable for common type urine analyzer.
Specimen requirements
1, Collecting the fresh urine with a container , as far as possible to shorten the storage time (no more than four hours to place the urine), to test the urine after centrifugation without the full mix.
2, the container by the detergents, disinfectants after treatment, should be fully dry after use with clean water.
3, when you save a urine sample, can not add acid, alkaline preservatives.
4, refrigerated or frozen urine samples should be brought to room temperature was measured after sufficient mixing.
5, urobilinogen and bilirubin due to instability, please collect a urine sample was measured within one hour.
6, when measured nitrite, should take morning urine or urine retention is better than four hours in the bladder.
7, check urobilinogen, the urine can be collected at any time, but 2-4 in the afternoon as well, so when the urinary excretion of urobilinogen most.
Test method
visual colorimetry:
Will test all test area into the fresh urine is fully blending, and immediately took out
2, leaning against the edge of the test strip container side, slipped more than urine;
3, holding a test strip, compared with colorimetric bottle sign on the table, record the test results in its determination time;
4, normal working conditions: ambient humidity 10 ºC ~ 30 ºC; relative humidity RH = 60%.
Urine analyzer colorimetric methods:
Please click urine analyzer used in the operating instructions for testing.
